Last time I found in Default Trace log file information like: “The predefined size of the shared memory monitoring slots for the thread system is reached: size[600], used[600], type[thread table]. Every thread started from now on will be fully functional but will not be visible in the MMC thread monitoring. You need to reconfigure the shared memory monitoring slots for threads“
